"I wrote many novels which … contained the element of the projected collective unconscious, which made them simply incomprehensible to anyone who read them, because they required the reader to accept my premise that each of us lives in a unique world."
- Philip K. Dick

A fascinating (and fantastic!) visualization of the long afternoon of our Earth.

The traverser, a gross vegetable-equivalent of a spider, was descending to the Tips…

The traverser was descending slowly, a great bladder with legs and jaws, fibery hair covering most of its bulk… It was like a god, with the powers of a god. It came down on a cable, floated nimbly down the strand trailing up into the sky.

As far as could be seen, cables slanted up from the jungle, pointing like slender, drooping fingers to heaven… They all trailed up in the same direction, toward a floating silver half-globe, remote and cool, but clearly visible even in the glare of eternal sunshine…

Unmoving, steady, the half-moon remained always in the same sector of the sky.

Read the discussion about the space elevator, which has a rich history before and after the idea's treatment by sf writers.

This flight of fancy on the part of Aldiss hearkens back to the earliest stirrings of science fiction. Take a look at the entry for weightlessness and the journey of the Gansas to the moon in Francis Godwin's 1638 novel The Man in the Moone.
